Rielly wasn't committed to bodying him. I have seen that guy take (prime) Lucic off the puck.
I know he's injured but damn.
I know what you're saying but physics has a lot to do with the situations.
Rielly skating backwards, Laine skating forwards.
Liane deked to his left and Rielly pivoted and made contact at that point. This stumbled both players a little but Tielly took the worst of it due to his angle and unstable position. Even then he managed to get down and his stick in position to block Laines first, and more dangerous shot while still forcing Laine into a worse shooting position.
It was an amazing shot and Freddie was out of position for it.
I just don't think that is a good example of a bad play from Rielly.
I'm personally still happy with Mo. He can still put up 50 points this season and imho still doing his job in the defensive zone. If anything I see him struggling more with the adjustments Keefe has made, but he will get there soon
